Abstract: An EGR system comprising at least one of an EGR cooler and an EGR valve is arranged above an intake manifold. A pair of facing surfaces which face each other with a space are provided at the EGR system attached to the intake manifold and the intake manifold. A damper plate having elasticity is arranged between these facing surfaces. The damper plate is configured to have a larger thickness than the above-described space and have a smaller Young's modulus than each of a lower-side facing-surface portion and an upper-side facing-surface portion, and the damper plate is clamped between the lower-side facing-surface portion and the upper-side facing-surface portion.
